\VEIGHING-WTACHINE Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed June 25, 1908. Serial No. HO/10.

T all whom it may concern:

Be it known that 1, CHARLES i. Dnnrsnr, a citizen of the United Statesof America, and a resident of the city of Riverside, in the county ofRiverside and State of California, have invented certain new and usefulImprovements in VVeighing-Machines, of which the following is aspecification.

This invention has particular reference to automatic weighing machines,and the priniary object thereof is the provision of a simple andefficient apparatus whereby large quantities of oranges may beexpeditiously and accurately weighed.

Further objects and advantages will be set forth as the descriptionprogresses and those features on which I desire protection defined inthe appended claims.

lVith reference to the accompanying drawings, wherein similar referencenumerals designate corresponding parts throughout, Figure 1, is a planview illustrating my invention in such form as now preferred by me,portions of some of the parts being broken away. Fig. 2 is alongitudinal sectional view taken on line 2 2 of Fig. 1. Fig. 3 is atransverse sectional view on line 33 of Fig. 2. Fig. 4 is a fragmentaryperspective view illustrating the releasable connection of the drivingmechanism connected for active operation, and Fig. 5 is a fragmentarysectional view of said connection illustrating the relative positions ofthe parts in effecting a releasing operation.

Reference numeral 1 designates a suitable frame, and 2, 2 indicatereceivers conveniently in the form of platforms having side wall 2 andyieldingly supported side by side for independent downward movement onsuitable weighing mechanism, which, as shown, comprises articulatedbeams as 3, suspended from rods 4 of said frame by link 5 and connectedwith respective counterbalancing levers 6 fulcrumed on frame bar 7 andhaving screw threaded engagement with weights 8. The receivers 2 aresuitably inclined endwise to effect discharge of the oranges by gravityand for this purpose legs 2 of proper length are provided on thereceivers and bear on respective lugs 3 of beams 3.

At the upper ends of receivers 2 I have shown an inclined feed way ortrough 9 having a flaring delivery end portion 9 common to bothreceivers and provided with a feed regulator in the form of a deflector10 which is secured to a vertical rock shaft 10 for angular adjustmentto direct the feed to the receivers alternately.

At the lower ends of the receivers are gates 11 which are adapted to thesame against discharge as the oranges are directed thereto. These gatesare swingably suspended on a rod 11 of frame 1 for opening and closingmovements and in connection therewith I provide means for effecting suchmovements correlatively with the adjustment of deflector 10 so that onel'CCGlVGl will be closed and have the feed directed thereto while theother receiver is open and the contents discharging.

VVhile the aforesaid operation of the feed controlling and dischargingmeans may be otherwise effected I preferably provide for this purpose acrank mechanism including oppositely disposed cranks 12 secured to ashaft 12 j ournaled on frame 1 and connected by rods 13 with. respectiverock arms 1 1 secured to gates 11. This shaft is furthermore providedwith a crank 12 which is connected by means of a rod 15 with an arm 5 ofshaft 10 to adjust deflector 1U simultaneously with the gates to cut offthe feed to the receiver whose gate is opened.

The relative proportions of the crank mechanism just described is suchthat the deflector and gates may be adjusted from one position of set tothe other by giving shaft 12 a half turn, consequently subquentadjustment of said parts may be efifected by completing the rotation ofthe shaft.

To effect automatic operation of the controlling means I preferablyemploy a driving mechanism embodying a releasable connection such asparticularly described and claimed in an application for patent signedby me on even date herewith and bearing Serial No. 440,409. The saidconnection includes companion carriers as an arm 16 and a disk 17secured to independently rotatable shaft sections as 16 and 17respectively journaled on frame 1. Section 17 I have shown connected bymeans of suitable movement reducing gearing 18 with shaft 12 to drivethe latter at a relative ratio of one half to one.

Associated with section 17 is a catch contrivance comprising a disk 19secured to said section, and a relatively fixed catch 20 in the form ofa spring bar normally engaging in a peripheral notch. of the disk tosecure the fied controlling mechanism in either position 0' set.

Secured to shaft section 16 is a pulley 21 for the application of powerto impart continuous rotary movementthereto, and related to both of theweighing mechanisms 1 provide a shipper mechanism including a rod 22which is adapted to set the releasable connection intermittently tooperate the feed controlling means as will later be understood.

At opposite sides of carrier 17 are curved arms 70 and 71 which aresecured at their rear ends to a common pivot 72 journaled in saidcarrier adjacent the rear end of a peripheral notch 73 thereof. Thesearms have their outward movement limited by a lug 72 of carrier 17.

Mounted on carrier 16 in slidable engagement with the edge walls of aradially disposed slot 60 thereof is a head 60 having pivotalengagement, as at 61, with one end of an L-shaped catch 62 whichprojects across the edge of carrier 17. Engaged with catch 62is a spring63 arranged to press inwardly upon the same directly over the head 60.

Secured to head 60 is a shoe 64 adapted during inactive operation of theconnection to ride upon arm 70 to carry catch 60 clear of notch 7 Sthesaid arm normally resting by gravity with its free end lying within theswee of said shoe upon a lug 74 of carrier 17 Rented to catch 62 is aspring pressed trip 65 swingably supported on shaft section 17 andnormally lying adjacent the forward edge of notch 73 with its upperbeveled end portion 65 in the path of a beveled end portion 62 of catch62 when the latter is engaged in said notch. The movement of trip 65with catch 62 is limited by a relatively fixed stop 66 which serves toretain the trip so that the catch will be forced outwardly to disengageit from notch 73 at the end of a complete revolution of carrier 17asindicated in Fig. 5.

Shipper rod 22 as shown, has pivotal connection with an arm 24 of aspring retracted rock shaft 23 journaled on frame l beneath the weighingmechanism and provided with arms 25 projecting in an opposite directionto arm 24. Engaged with arms 25 are screws 26 adapted for contact withrespective brackets 3 of the beams 3 for downward movement to turn shaft23 and thereby elevate rod 22 when either one of said beams isdepressed. Rod 22 has slidable engagement with a bracket 27 of frame 1and is provided with a laterally projecting termination 28 adapted toengage and swing arm 71 outwardly and thereby move arm clear of the pathof shoe 64 for active operation of the reeasable connection when eitherof the receivers 2 have been properly loaded.

Assuming that the feed is passing to the receiver on the left in Fig. 3and shaft 16 rotating, the operation of the machine would besubstantially as follows. Catch 62 rides on carrier 17 and shoe 64 onarm 17 to carry the catch clear of notch 73 until sufficient load hasbeen applied to the receiver to depress its supporting beam 3 and effectmove ment of rock shaft 23 to operate rod 22 and thereby move arm 70clear of the pathof shoe 64 and permit catch 62 to engage in notch 73,when further movement of the catch with shaft 16 will operate shaft 17and connected mechanism to shift the deflector 10 and gates 11 to freethe contents of the loaded receiver for discharge and effect loading ofthe other. As catch 62 is completing its active revolu tion it engagestrip 65 and moves the same into engagement with stop 66 therebyeffecting release of the catch from carrier 17 as hereto described ascatch 20 engages its seat in disk 19 and arms 70, 71 returns to normalposition by gravity.
